Featured topic page <a href="Pore%20pressure%20prediction%20using%20seismic">Pore pressure prediction using seismic</a> Drilling engineers require estimates of the fluid pressures that they are likely to encounter in any given well to anticipate mud weights required to maintain optimal drilling rates and safety. In addition, the locations of anomalous pore-pressure regions are of interest in exploration because they often correlate with highly productive “sweet” spots in otherwise tight gas sands. <a href="<a href="http://petrowiki.org/Pore_pressure_prediction_using_seismic" alt="http://petrowiki.org/Pore_pressure_prediction_using_seismic" title="http://petrowiki.org/Pore_pressure_prediction_using_seismic">http://petrowiki.org/Pore_pressure_prediction_using_seismic</a>" alt="<a href="http://petrowiki.org/Pore_pressure_prediction_using_seismic" alt="http://petrowiki.org/Pore_pressure_prediction_using_seismic" title="http://petrowiki.org/Pore_pressure_prediction_using_seismic">http://petrowiki.org/Pore_pressure_prediction_using_seismic</a>" title="<a href="http://petrowiki.org/Pore_pressure_prediction_using_seismic" alt="http://petrowiki.org/Pore_pressure_prediction_using_seismic" title="http://petrowiki.org/Pore_pressure_prediction_using_seismic">http://petrowiki.org/Pore_pressure_prediction_using_seismic</a>">Learn more....</a> In the news <a href="PetroWiki%20news">PetroWiki news</a> <a href="<a href="http://www.spe.org/jpt/article/8415-8415/" alt="http://www.spe.org/jpt/article/8415-8415/" title="http://www.spe.org/jpt/article/8415-8415/">http://www.spe.org/jpt/article/8415-8415/</a>" alt="<a href="http://www.spe.org/jpt/article/8415-8415/" alt="http://www.spe.org/jpt/article/8415-8415/" title="http://www.spe.org/jpt/article/8415-8415/">http://www.spe.org/jpt/article/8415-8415/</a>" title="<a href="http://www.spe.org/jpt/article/8415-8415/" alt="http://www.spe.org/jpt/article/8415-8415/" title="http://www.spe.org/jpt/article/8415-8415/">http://www.spe.org/jpt/article/8415-8415/</a>">Guest Editorial: The Six Minds of a Whole New Engineer</a> by David E.

What is PetroWiki? PetroWiki was created from the seven volume <a href="<a href="http://store.spe.org/Petroleum-Engineering-Handbook-Volumes-I-VII-Print-Set-P126.aspx" alt="http://store.spe.org/Petroleum-Engineering-Handbook-Volumes-I-VII-Print-Set-P126.aspx" title="http://store.spe.org/Petroleum-Engineering-Handbook-Volumes-I-VII-Print-Set-P126.aspx">http://store.spe.org/Petroleum-Engineering-Handbook-Volumes-I-VII-Print-Set-P126.aspx</a>" alt="<a href="http://store.spe.org/Petroleum-Engineering-Handbook-Volumes-I-VII-Print-Set-P126.aspx" alt="http://store.spe.org/Petroleum-Engineering-Handbook-Volumes-I-VII-Print-Set-P126.aspx" title="http://store.spe.org/Petroleum-Engineering-Handbook-Volumes-I-VII-Print-Set-P126.aspx">http://store.spe.org/Petroleum-Engineering-Handbook-Volumes-I-VII-Print-Set-P126.aspx</a>" title="<a href="http://store.spe.org/Petroleum-Engineering-Handbook-Volumes-I-VII-Print-Set-P126.aspx" alt="http://store.spe.org/Petroleum-Engineering-Handbook-Volumes-I-VII-Print-Set-P126.aspx" title="http://store.spe.org/Petroleum-Engineering-Handbook-Volumes-I-VII-Print-Set-P126.aspx">http://store.spe.org/Petroleum-Engineering-Handbook-Volumes-I-VII-Print-Set-P126.aspx</a>">Petroleum Engineering Handbook</a> (PEH) published by the <a href="<a href="http://www.spe.org" alt="http://www.spe.org" title="http://www.spe.org">http://www.spe.org</a>" alt="<a href="http://www.spe.org" alt="http://www.spe.org" title="http://www.spe.org">http://www.spe.org</a>" title="<a href="http://www.spe.org" alt="http://www.spe.org" title="http://www.spe.org">http://www.spe.org</a>">Society of Petroleum Engineers</a> (SPE). PetroWiki preserves the PEH content in unaltered form (page names that start with PEH:), while allowing SPE's membership to update and expand content from the published version. Pages that do not have PEH: at the beginning may have started with content from the PEH, but have been modified over time by contributors to the wiki. Content in PetroWiki is <a href="PetroWiki%3AModeration">moderated</a> by at least two members with subject matter expertise.

How can I contribute to PetroWiki? PetroWiki is a living document and therefore the content should be enhanced to include newer technologies and current information. Share your knowledge with others and help update PetroWiki at the same time! You can't "break" the wiki. Follow these basic steps to get started: </dt> Log in </dd> Search for the topic of your choice </dd> Open the topic page </dd> Make changes </dd> Save </dd> </dd> </dd> Adding links to good papers in OnePetro and elsewhere is a great way to enrich existing content pages. Creation of pages about specific fields are welcome. Knowing the basics of the reservoir and how the field was developed over time can provide valuable information to others. (See <a href="Prudhoe%20Bay%20field">Prudhoe Bay field</a> and <a href="Kuparuk%20River%20field">Kuparuk River field</a> as examples) If you are an SPE professional member, you must log in. [Use your SPE website login.] <a href="Help%3AEditing%20a%20page">Help with editing</a> Pages that start with PEH: cannot be edited. For more information, see <a _fcknotitle="true" href="PetroWiki%3AFrequently%20asked%20questions">PetroWiki:Frequently asked questions</a> Content categorization - SPE has finalized a technical <a href="Taxonomy">taxonomy</a> that is being used in PetroWiki, OnePetro, and other SPE content.
